Odi....No misuderstanding at all...you cannot fly IFR in IMC if your licence prohibits it (no IR or IMC). You can however fly IFR in VMC without an IR / IMC as you are actually still VFR. If you hold an IR or IMC you can fly IFR in IMC or VMC.
VFR = Visual flight rules
IFR = instrument flight rules
VMC = Visual Met conditions
IMC = Instrument Met conditions
Normally you don't get people wihout an IR or IMC filing IFR.
